VEGETABLE SHREPDER Application filed December 18, 1929. Serial-No.415,066.

This invention relates to vegetable and meat-cutters and comminutors,and more es-.

pecially to an improved type of grater for domestic use. 5 An object ofthe invention is the provision of an unusually simple and inexpensiveshredder, which is possessed of novel, meritorious features-such asremovability of the shredder plate from the frame of the instruferentshredder plate; withthe result that several different classes of workmay be performed by my improved shredder, by merely selecting andmounting in operative position, the appropriate type of shredder plate.Another object is the provision of a shredding device in which theshredder plate is removable as described, in which the means forremovably mounting the plate upon the frame, are so designed that theselected plate may be substantially instantaneouslymounted in operativeposition upon the plate, and

removed therefrom.

The invention possesses other objects andadvantageous features, some ofwhich, with those enumerated, will be set forth in the followingdescription of the inventions particular embodiment which is illustratedin the drawings accompanying and forming apart of thespecificatlon.

Referring to the drawings:

Figure 1 is a front elevation of a shredding device constructed inaccordance with the principles-of the present invention.

Fig. 2 is a rear elevation. I

Fig. 3 is a longitudinal, medial sectional view taken upon t e line 3-3of Fig. 1, with the direction of view as indicated. I

Fig. 4 is a front elevation of the frame of bodiment of the. invention,my shredding dement, to permit its being replaced by a dif-- theshredder after the shredder plate has vice comprises a frame 11, and ashredding plate 12 adapted to be removably mounted thereupon. The frame11 is constructed of .a suitable length of wire bent in such a manner asto form a pair of opposed, spaced side members 13, which are straightthroughout a material length thereof, and which are disposed inparallelism with each other. The

side members 13 are retained in spaced relationship by means of a lowerend 14, which, as shown upon Fig. 3,is offset from the common plane ofthe side members 13, being set backtherefrom by angular extensions 16 oftheside members 13. The side members 13 are retained spaced at theirupper ends, through the expedient of a portionl? of wire extendingtherebetween, thisportion 17 having a loop 18 therein to provide ahandle, permitting the frame 11 to be readily and easily retained inconvenient operating position by one hand. The handle 18 is deflected soas toextend angularly rearwards from the frame'll, as is also best shownupon Fig. 3. From the base of the handle 18, the portion 17 of the wire,slopes to meet the upper ends of the side members 13 of the frame, sothat in effect, the upper end of the frame 11 is pointedhwith the handle18 extending from the point. The frame 11 is also provided with a pairof stops .19,spac,ed equally from the lower end 14 of the frame anddisposed upon the opposed side members 13, these stops being utilized tolimit the downward movement of the shredding plate 12 when mounted inoperative position upon the frame 11.

The shredding plate 12, a plurality of which, of different types, may beadapted for mounting upon a single frame 11, is in the form of apreferably flat plate 21. 'This plate 21 is adapted to be easily andremovably mounted upon-the frame 11, through the expedient of curlingthe two lateral edges 23 to form flanges 24 extending rearwards ,fromthe plate 21, preferably throughout the entire length of the two sideedges 23. The 'plate 21 is of such width that the effective distancebetween the two opposed flanges 24, corresponds to the width of theframe 11, thereby permitting the side members 13 of elevated from theplane of the plate.

as to substantially conform to the cross-sectional configuration of theWire of which the side mbmbers 13 are formed, thus establish=' ing moresecure engagement therewith; and each of thefla-nges 24 is of suchdimensions that it extends substantially half way around the associatedside member 13. As a result of this construction of the flanges 24, aselected shredding plate 12 may easily be mounted upon, or removed fromthe frame 11, simply by sliding the plate 12 longitudinally onto theframe 11, with each of the side members 13 of the frame 1 ing within thecurvature of one of the anges 24:. The plate 12 should be slid onto theframe 11 from the top end, and the sliding of the plate continued untilthe bottom edge of the plate engages the stops 19, the parts preferablybeing so proportioned that when the bottom edge of the plate 12 soengages the stops 19, the upper edge 26 of the plate, which also ispreferably pointed, will substantially conform to the upper end of theframe ll- A flange 27 may be formed upon each of the sloping sides ofthe upper'edge 26, by curling these edges downwardsthroughout the majorportion of their length, in such a manner'as to cause the flanges 27 toengage the sloping portions of the upper portion, 17 of the wireframework 11. The parts should be so proportioned that the flanges 27engage the upper portion 17 of the wire framework, at the same time thatthe lower edge of the shredding plate 12 engages the stops 19; with theresult that the stops 19 and the flanges 27, cooperate with each otherin retaining theshredder late 12 in operative position upon the wirerame 11.

The shredding plate 12 is provided with preferably a plurality of-cutting edges 31. These cutting edges may conveniently be formed bypunching or otherwise forming a plurality of holes 32 in predeterminedarrangement throughout theefiective area of the plate 21. Preferably,the holes 32 are arranged in rows as illustrated. After the holes 32have been punched, the material of the plate 21 immedlately below eachof the holes 32, is pressed toward the front of the plate, e.,lisstruckupwards therefrom, so

that the lowermost edge of each hole 32, is

The edges 31 thus formed, will be relatively sharp because of the factthat as the materialof the plate is struck upwards from the planethereof, it is necessarily stretched to a certain extent, reducing itsthickness as compared to the thickness of the remainder of the plate.Preferably, the portion 33 of the plate 21, which is struck upwardsbelow each of the holes 32, corresponds in width to the diameter of theassociated hole 32, but is mate 'rially longer,'thereby facilitating thepassage through the hole 32, of the shred or slice of material which theassociated cutting ed e 31 has cut.

t is obvious that by supplying a plurality of the'shredding plates 12with them respective holes 32 of different sizes, and with the cuttingedge 31 struck upwards different distances from the plane of therespective plates, shreds and/or slices of various thicknesses andwidth,may be formed.

Each of the plates 12 is reinforced along its loweredge byforming a bead36 thereon. This may easily be done by simply curling the lower edgeover against the rear surface thereof, as shown upon Figs. 2 and 6."Furthermore, each of the plates 12 is provided with an aperture'37adjacent the upper edge .26 thereof, to facilitate hanging one or aplurality of plates in any convenient location.

Whereas the device is designed primarily for slicing and shreddingvegetables, it will readily be appreciated that it may be employed forperforming this operation upon a wide variety of materials. It isutilized by supporting the frame 11 with the handle 18 thereof, in onehand, and the offset lower end 14 resting upon a suitable supportingsurface which may be the bottom of a,bowl or other receptacle into whichthe shredded material is to fall. The article to be shredded is thenreciprocated up and down, in contact with the front face of theshredding plate 12, so

that it encounters the various cutting edges 31, each of which cuts ashred of material from the article. Each of these shreds passes throughthe associated hole '32 and falls into the receptacle or onto thesupporting surface upon which the frame 11 is supported.

Owing to the relatively large number of I cutting edges 31 which may beprovided in each of the shredding plates 12, this shredding operation iscarried out with the utmost ease and rapidity. The removability of theshredding plates 12 from the frame 11,. permits not only the selectionof the desired shredding plate to produce shreds of the desired size,butit also materially facihtates cleansing and sterilizing the entiredevice.

It is to be understood that the details of the invention as hereindisclosed, are subject to alteration within the spirit or scope of theappended claims.
